Abstract: 533,071. Sound and picture recording apparatus. KOLB, O. K. (Beer, P. F., and Anneberg, P. V. I. P.). Oct. 5, 1939, No. 27273. [Class 40 (ii)] [Also in Groups XXXVII and XXXV] In a combined picture and sound recording camera, the film 31 is driven by a motor 1 comprising a winding 22 carried by a member provided with pole shoes 21, and co-operating with a stator 20, the winding 22 being energized from a battery 5 through an interrupter 23 mounted on the motor shaft. The speed of the motor is determined by an electromagnetic vibrator 2 through which the motor is additionally supplied from the battery 5. Thus the motor operates as a synchronous motor running in synchronism with the operation of the vibrator and at speeds below this develops a torque sufficient to attain the synchronous speed. The vibrator additionally supplies current through a step-up-transformer, a rectifier and smoothing circuit, for use with an amplifier associated with the apparatus. Further it may energize a glow lamp cooperating with a disc on the motor shaft for observing synchronous operation. A member 61 may engage recesses 60 in a disc 59 on the motor shaft to hold the motor stationary in a position of maximum torque. A centrifugal device may control a resistance to prevent super-synchronous operation. A flywheel 34 coupled to a roller 35 driven by the film stabilizes the speed and vibration is absorped by a spring biassed arm 45 carrying rollers 36, 37 engaged by the film. The stator of the motor may be suspended resiliently. Specifications 249,627, [Class 40 (ii)], 506,654 and 510,043 are referred to.
